y

GENERAL. The Cober 606 is a versatile, High-Power Pulse Generator that produces a broad range of excellent waveshape pulses at peak powers of up to 31 Kw. Very fast rise and fall times, high repe-tition rates, and a wide range of pulse widths are obtainable. The unit is capable of operation over the full range and at either negative or positive polarities without the use of costly plug-ins. The above and many additional features make the Cober 606 the most flexible and useful high-power pulse generator available today.

The 606 is complete with a pulser module for se-lecting the pulse width and rep rate, or the user may inject his own 10-volt external pulse. In fact, the 606 may be provided without the pulser module for those who desire to use their standard low-level laboratory units.

OPERATIONAL FEATURES

The output from the 606 is continuously adjustable from 0 to 2,500 volts at an output current of 12.5 amperes. The output voltage is read directly on a front panel meter, and a 1000:1 capacitance divider allows scope monitoring of the output waveshape. The pulse width is variable from 50 nanoseconds to 10 milliseconds, and the repetition rate is adjust-able from a single shot to 1 MHz. Rise time is adjustable upwards from 20 nanoseconds. "Float-ing Deck" circuitry allows 5 KV D. C. isolation of the pulse from ground and permits either positive or negative pulse polarities, as selected by the

operator. No accessories are required for up to 5 KV D.C. isolation or pulse polarity reversal. Pulse transformers are available in the event higher D.C. isolation is desired or for other voltage and cur-rent combinations.

Overload circuits, zero start interlocks, and fusing are some of the safety features that provide full protection to equipment, load and personnel.

APPLICATIONS The Model 606 is a precise tool for research and testing. Specific applications include use as a power source for solid-state devices such as Gunn diodes, solid-state lasers and electro-optical modu-lators; driving source for gridded and cathode-pulsed power tubes, particularly microwave tubes. The 606 is used for performing destructive or non-destructive testing of electrical and electronic components and for determining their electrical and life characteristics. The high voltage and pow-er of the 606 makes it ideal for pulsing gas lasers, plasma tubes and gas discharge devices. The high rep rate capability of the 606 makes it especially useful for applications where pulse coding is de-sired — bursts with pulse-to-pulse spacing of less than 1 microsecond are available. The 606 also finds application in the pulse testing of magnetic components, nuclear research and as an all-pur-pose source of high power pulses for the labora-tory. It is available with or without the low-level pulser and in rack mounting or bench top con-figurations.

OTHER COBER PULSE GENERATORS In addition to the 606, you should also consider the Cober 604-A and 605-P to determine the most suit-able pulse generator for your application. The 604-A is characterized by its high pulse fidelity into loads of varying impedance. This is because the 604-A has built-in pre-loads to allow an opti-mum match to the pulse generator load—a feature particularly useful when driving devices such as Pockel cells and crystals which are capacitive in nature.

The 605-P's output power of 22KW is ample for most applications that don't require the power of the 606. In all other material respects the 605-P is identical to the 606. It too has the Cober ex-clusive "floating deck" circuitry that allows both positive and negative polarity and the 5KV isolation without the need for expensive accessories that degrade the pulse shape.
